Original applicationfiled December 22,1922, Serial No. 608,420. Dividedand this application filed February 17, 1923.

To all whom it may concern: I,

Be it known that I, VALTER S. ADAMS, a citizen of the United States, anda resident of the city and county of Philadelphia and 6 State ofPennsylvania, have invented a cer" tain new and useful Improvement inCar Trucks, of which the following is a specification.

This application is a division of my oopending application for patent,Serial No.

608,420, filed December 22nd, 1922.

This invention relates to an improvement in car trucks, and has for itsobject to provide a novel form of spring-supporting 16 means which willavoid jerky and unpleasant lateral movements or side sway of the carbody; and which will remove the twisting strains usually imposed uponthe leaf springs of the truck during the jerky lateral movements of thecar body on rough stretches of track.

A further object of my invention is to provide a spring-supporting meanswhich will hold the sprin securely and prevent 2 distortion thereof atall times.

with these objects in view, I have devised the particular arrangement ofparts hereinafter set forth and more particularly pointed out in theclaims appended hereto.

Reference is to be had to the accompanying drawing, forming a parthereof, in which-- Figure 1 is a side elevation of a portion of a cartruck, showing my improved spring suspending means, and

Figure 2 is a sectional view on the line 2-2 of Figure 1, looking in thedirection of the arrows.

Throughout the various views of the drawing, similar referencecharacters designate similar parts.

In the embodiment of my invention as disclosed in the accompanyingdrawing, the upper member of the truck side frame 4 is disclosed at 1,and the lower member of said frame is indicated at 2. The

truck bolster is indicated at 3 and it is,

Serial No. 619,556. r,

The ends of the leaf spring 7 are each supported upon a bracketorsp'ring-seat 8, and each of said brackets is provided with a pair ofupwardly extending ears 9 between which the lower end of a curved linkor hanger 10 is pivoted by means of the bolt 11. The link or hanger 10extends upwardly behind the frame member 1 and has its upper end bent orcurved forwardly to extend over the top of the frame member 1.

At 12 is shown the hanger-supporting bracket which is provided with apair of spaced lugs 13 which straddle the frame member 1 and are securedthereto by a bolt 14, which extends through the lugs 13 and through theframe member.

The bracket 12 is provided with a pair of spaced upwardly extending ears15, between which the upper end of the hanger 1O is pivoted on the bolt16. The ends of the spring are supported by the hangers 10 as describedabove, and as such hangers are pivoted at their upper and lower ends itwill be apparent that during side sway of the bolster, the spring 7 willride horizontally, and the twisting stresses usually imparted to a fixedspring, will be avoided.

The use of curved or bent spring-supporting hangers permits the springto be supported directly below the side frame member 1, or even outsideof the same, without requiring the use of a frame member ofsubstantialthickness which would have to be perforated to permit astraight hanger to extend directly downward through it.

From the foregoing, it is obvious that my invention is not to berestricted to the exact embodiment shown, but is broad enough to coverall structures coming within the scope of the annexed claims.

Having described my invention, what I claim is 1. In a car truck, atruck frame, a bracket secured thereon, a link having one of its endspivoted in said bracket and extending downwardly on one side only ofsaid frame, and a spring seat pivotally secured to the lower end of saidlink.

2, In a car truck, a truck frame, a bracket secured to the upper memberof the frame and projecting upwardly above the same, a link having itsupper end pivotally secured in said bracket, said link being bent toextend to one side of the frame member and projecting downwardly belowthe same, and a pivoted spring-seat on the lower end of said link.

3; In a car truck, a truck frame, a bracket secured to said frame, saidbracket being provided with a pair of ears, a link having one of itsends pivoted between said ears, said link being bent to extend from saidbracket behind the frame and below the upper member of said frame, aspring seat pivotally supported on the lower end of said link, and aleaf spring having one of its ends supported on said seat.

4. Ina car truck, a truck frame having an upper member, a pair of spacedbrackets secured thereon, a link pivoted in each of said brackets, eachof said links extending to one side of the frame member and projectingdownwardly below the same, a spring seat pivotally secured to the lowerend of each of thelinks, and a leaf spring having its ends supportedupon said seats.

Signed at the city and county of Philadelphia, State of Pennsylvania,this 15th day of February, 1923. 1
